44 Claims.

This invention relates to coating machines and is herein illustrated as embodied in a machine for applying cement to bevel edged rubber soles.

The rubber soles which are utilized in the manufacture of tennis shoes, for example, as well as those employed for rubber boots, artics and the like, are made of partly cured rubber stock and are cut out with their edges rather widely and sharply beveled, usually on the side of the sole which is to be secured by cement to the shoe. The application of cement to the attaching surface and the beveled edge of the sole has usually been carried out by hand. It will be understood that rubber soles of this type are naturally limp and very flexible and, furthermore, that the sharply beveled edge of such soles is even more flexible, while the soles usually vary in thickness in different parts, being thinner at the shanks and thicker at the heel parts. It is difficult for a hand operator, therefore, to obtain a very large production combined with a uniform coating and there is, furthermore, a very substantial danger that the outer or tread surface of the soles will be soiled.

Accordingly, one important object of the invention is to provide a coating machine wh1ch will satisfactorily coat the attaching surface and the surrounding beveled edge of a piece of work such as a sole and will obtain an increased production at less cost.

To this end one feature of the invention resides in a machine for coating soles having means for feeding the soles in the general direction of their length and having an endless coating applying I member which is moved to carry an active portion thereof continuously completely across the faces of the soles in a narrow path transversely thereof, means being provided to apply coating material to the applying member.

Another important feature of the invention resides in construction and arrangement employing a fiat-surfaced driven coating brush the axis of which is tilted with respect to a work support beneath the brush whereby one side of the brush will sweep transversely across successive portions of a piece of work presented to the brush, together with means for supplying coating material to the brush. As the work is moved relatively to the brush to cause successive portions thereof to be coated, such movement of the work in the illustrated machine being substantially radially of the brush, the brush sweeps up over the beveled edge of the work and then across its flat surface to apply a uniform coating without danger of smearing the under surface.

In accordance with another feature of the invention, the coating material is supplied to the annular brush of the illustrated machine at a point below the brush, thereby avoiding any difficulties in 1 he pply of coating material from a point overhead, and greatly simplifying the machine. When the machine is to be utilized for beveled edged rubber soles, and as herein illustrated, it is provided with a pair of concentric annular brushes rotating in opposite directions and, therefore, arranged to coat the beveled edge of the ole at opposite sides of the sole as well as the intermediate surface of the sole. As illustrated, also, the plane of the work support is tilted with respect to the axes of these brushes so that the active forward portions of the brushes sweep across successive portions of the work, which pieces are then carried forward beneath the elevated rear edges of the brushes without contact therewith.

To assist in increasing the production of the machine the work support of the illustrated machine is in the form of an endless work supporting and conveying belt. There is a tendency for the annular brushes to produce lateral displacement of pieces of work on said belt as the brushes wipe up over the beveled edge of and then sweep across the flat surface of a sole. Accordingly, another feature of the invention resides in improved means for preventing lateral displacement of the work relatively to the belt, such means in the illustrated machine comprising rolls cooperating with the work supporting conveyor and arranged one in front of the line of action of the coating brushes and the other back of the coating brushes as the pieces of work progress from one side to the other thereof. The illustrated roll which is disposed within the brushes is provided with sharp ridges to avoid removing coating material from the already treated pieces of work.

Another feature of the invention resides in a novel arrangement for supporting one end of the conveyor belt which enables the operator readily to adjust the supporting means so as to vary the relative tilting or angular relation of the surface of the supporting belt and the surface of the brushes, to the end that the brushes may be brought into an ideal contacting relation with the soles at the active portion of said brushes and ample space provided between the exit or inactive side of the brushes and the support. In the illustrated arrangement, this adjustment is provided by mounting one of the conveyor rolls upon an adjustable bracket pivoted about the axis of the other roll and, as shown, there is also provided means for adjusting the brushes upon their axes to compensate for wear and to get the desired relation of the tips of the bristles to the work support. Usually, and as illustrated, the adjustable supporting bracket also carries with it the rolls which prevent lateral displacement of the pieces of work and cleaning rolls which together with a separate scraper clean the belt for re-use.

In the illustrated machine, the annular brushes overhang the lateral edges of the conveyor belt and are supplied with cement from a subjacent receptacle by means of supply rolls which dip in the receptacle and convey the cement to the bristles of the brushes, the respective brushes being supplied on opposite sides of said belt. To render easy the care of the machine, the illustrated supply receptacle is made removable and supply rolls which, as illustrated, are journaled in the receptacle, are provided with a detachable driving mechanism so that said rolls and the receptacle may be taken out together.

These and other features of the invention 'will be better understood from a consideration of the following specification taken in connection with the accompanying drawings in which,

Fig. 1 is a side elevation of the machine with parts broken away and in section;

Fig. 2 is an end elevation at the delivery end of the machine; and

Fig. 3 is a plan view of the machine.

Pieces of work, such as rubber soles 10 having 7 outwardly beveled edges around the whole peripheries of the soles are laid upon a work support in the form of an endless belt 12 supported upon rolls 14 and 16. The roll 14 is carried in a machine frame 18 while the roll 16 is mounted in adjustable journal boxes 20 carried at the outer ends of swinging bracket arms 22 and 24. These bracket arms are joined by a plate 26 near their outer ends and are pivoted on a shaft 28 which forms the axis of the roll 14. The worksupporting belt 12 may conveniently be constructed of sheet brass or the like and held under tension by adjustment of the positions of the journal boxes 20 by means of nuts 30 (Figs. 1 and 3).

A coating, such as of cement, is applied to the flat upper surface of each sole 10, which surface is the attaching surface when the sole is assembled in the shoe and also to the sharply beveled edges upon opposite sides of the sole which later are folded over the lower margin of the shoe to produce a rolled edge. The application of cement to the upper surface and to the beveled edge surfaces offers some difficulty because of the different planes in which said surfaces lie but it may be successfully accomplished by means of one or more fiat-surfaced, endless, annular brushes 32 and 34 herein shown as of substantial diameter and concentric to each other, said brushes being driven in opposite directions so that the active portions thereof sweep in opposite directions transversely continuously across each sole in a narrow path to apply coating material to the lateral edges and the upper surface of the sole. The relative position of the supporting belt 12 and the lower ends of the brush bristles at one side of the brushes will preferably be such that they almost touch in order that the brushes shall act upon the full width of the beveled edges of the sole as they ride up over said edges and then sweep across the upper surface of the sole. While a single brush may be found satisfactory in treating the upper surface and the beveled edges upon opposite sides of a sole, a pair of brushes will more surely apply the cement to the oppositely beveled edges, and will also be useful in applying successive coats to the flat upper surface of the sole.

These brushes 32 and 34 are supported in a hinged arm 36 which is pivoted in a bracket 38 (Fig. 2) and supported at its other end by means of a bracket 40 to which it is detachably' secured by means of a swinging bolt and a nut 42. When it is desired to lift the brushes for cleaning, the nut 42 is released and the arm 36 swung up until a hook 44 on the arm can be engaged with a latch 46 on the frame of the machine to hold the arm and brushes in raised position.

The lower brush 34 is keyed to an upright shaft 48 (Fig. 2) to which there is splined a mitre gear 50 meshing with a gear 52- upon a shaft 54 journaled in the frame of the machine as well as in said arm 36 and driven from a sprocket 56. It will be noted from Fig. 3 that the shaft 54 has a universal joint 58 to permit tilting movement of the arm 36. The upper and outer brush 32 is keyed to a sleeve forming an extension of another mitre gear 60 (Fig. 2) which is also meshed with the gear 52 and driven in an opposite direction thereby. This mitre gear 60 and its sleeve turn freely about the shaft 48. In order to allow a correct original setting with respect to the work-supporting belt and to permit adjustment to compensate for wear of the brush bristles, provision is made for the vertical adjustment of the two brushes by means of a sleeve 62 threaded externally to engage a portion of the arm 36 and provided with a locking collar 64, said sleeve being rotatably mounted upon an extension of the shaft 48 and held against longitudinal movement thereon by a nut 66.

The driving of the brushes and of the worksupporting belt is effected from an electric motor or the like positioned in the base of the machine. This motor transmits its power through suitable reduction gears 72 to a chain 74 (Fig. 1) transmitting power directly to the shaft 28 upon which the belt roll 14 is mounted. Another chain 76 connects the shaft 28 with a hollow shaft 78 to be later described, journaled in a bearing block 79 and the frame of the machine. Upon this shaft there is keyed a double sprocket 80 and the other half of this sprocket transmits power by means of a chain 82 to the sprocket 56 at the top of the machine to drive the brushes 32 and 34.

Cement or other coating material is supplied to the brushes 32 and 34 from a receptacle 84 supported on ledges 86 and 88 in a chamber which is practically enclosed by the frame of the machine and by a bottom cover 90. An end plate 92 attached to the receptacle serves as a door for the chamber. This receptacle 84 provides journals for a shaft 94 (Fig. 2) carrying supplying disks 96 and 98 which pick up cement from the receptacle 84 and carry it to delivery disks 100 and 102 which are mounted on a. transverse shaft 104 (Fig. 2) carried in loop-shaped brackets 106 and 108 bolted to the inner sides of the frame. The upper portions of the disks 100 and 102 contact respectively with the bristles of the brushes 32 and 34 upon opposite sides of the work supporting belt 12 thus providing for an adequate supply to the oppositely rotating,

brushes at portions which are approaching the work and without danger of dripping of cement such as might occur in case it were attempted to supply cement from overhead. In order to permit removal of the receptacle, the shaft 94 is adapted to be releasably connected to the hollow shaft 78 already mentioned by means of a sliding plunger 110 carried within the hollow shaft 78 and having a tongue 112 in its inner end to coact with a suitable slot in the end of the shaft 94. This plunger 110 is spring-pressed in a direction to connect the shafts 78 and 94 and is splined to the hollow shaft 78. The

plunger 110 is provided with an operating handle 114 outside the frame of the machine. This handle 114 is rotatably mounted on the plunger 110 and is provided with an inwardly projecting lug 116 adapted to engage a corresponding slot in the enlarged end 118 of the hollow shaft 78. When the handle 114 is pulled out to disengage the driving connection between the shafts 78 and 94, it may be given a partial rotation to cause the lug 116 to rest on the enlarged end 118 of the hollow shaft 78 to hold the plunger 110 against the tension of its spring. When it is desired to re-engage the parts after the cement receptacle has been replaced, then the handle 114 is again turned so that its tongue 116 will drop into the slot of the enlarged end 118 and allow the tongue 112 on the plunger 110 to re-engage the shaft 94. At the other end of the shaft 94 there is provided a locating device in the form of a removable stud 120 which passes through the frame of the machine and enters a recess in the end of the shaft 94. It will be noted that the shaft 104 carrying the upper disks is connected to the driven shaft 78 carrying the lower disks by means of intermeshing gears 122 and 124. As a consequence the pairs of disks 9698 and 100-102 are driven in opposite directions and the upper portions of the peripheries of the upper disks 100-102 move in such directions that they oppose the directions of movement of the bristles of the coating brushes so that the cement is wiped onto said brushes and an adequate supply therefor insured.

Because of the lateral movement of the brushes with respect to the soles upon the belt 12 there is some tendency to the-lateral displacement of said soles. This is counteracted, however, by means of rolls 130 and 132 (Fig. 1) which contact with the upper surface of the successive soles 10 just in front of or outside and just back of or inside the line of action of the brushes to prevent lateral displacement and to insure the satisfactory progressive movement of the soles with the supporting belt 12, said rolls co-acting with the belt to that end. The roll 130 is nurled and is mounted for free rotation by means of studs 134 in a swinging arm 136 extending from side to side of the belt and pivoted at its ends upon brackets 138 and 140 attached to the long bracket arms 22 and 24 respectively. These brackets 138 and 140 also provide for the support of backing rolls 142 and 144 underlying the belt 12 to prevent downward deflection of the belt and make the action of the rolls 130 and 132 more positive. Adjustable studs 146 upon the respective brackets 138 and 140 engage the sides of the swinging arm 136 to support the roll 130 in a position slightly elevated above the belt 12 so that the advancing beveled edge of a sole 10 will not be curled up upon engagement with said roll 130 but will progress far enough under the bite of the roll 130 to insure the coaction of said roll with the belt in advancing the sole to the action of the brushes, it being understood that the weight of the roll 130 and associated parts is depended upon to hold said roll in engagement with successive soles. It is noted that the roll 132 is made up of series of disk-like members (Fig. 3) to avoid removing cement from the already coated sole, said members being journaled in a curved extension 146 (Fig. 3) of a transverse arm which has depending terminal portions 148 (Fig. 1) which are pivoted on upwardly extending lugs integral with the brackets 106 and 108 which are bolted to theinner sides of the frame.

When pieces of work have been coated, they pass under the inactive portions of the brushes 32 and 34, because of the relative inclination of the belt 12 to the plane of the bottoms of said brushes, and then they are removed from the belt 12 by means of a work stripper 150 carried on pivoted arms 152 which may be adjustably mounted in brackets 154 secured to the frame of the machine. Spring pressed abutment screws 156 are provided to engage the opposite sides of the upper end of the arms 152 and said arms are held in the brackets 154 by means of removable studs 158.

The surface of the belt 12 is bound to become coated with cement to a substantial extent, partly because of the fact that the soles do not completely cover the belt and partly because there may be spaces between the successive soles. At any rate, a series of scraper blades 160 separated at their ends by spacing blocks are bolted on a swinging carrier 162 supported by detachable studs 164. The blades 160 are thus held by gravity in engagement with the belt 12 where it is passing over the roll 14. A handle 166 is provided for the carrier 162 so that said carrier may be lifted up when it is desired to remove the recep tacle 84, in order to avoid interference between the disks 96 and 98 and said scrapers 160. The cement which is taken oil" the belt by the scrapers 160 passes down between the respective spaced scraper blades directly into the receptacle 84.

In order to perfect the cleaning of the outer surface of the belt 12 before it comes back into position for the reception of additional pieces of work a series of cleaning rolls 170 (Fig. 1) are provided which may be covered with friction tape or the like to provide a tacky surface to which particles of cement will adhere. These rolls contact with the idle run of the belt andare journaled in a swinging carrier 172 pivoted upon the arms 22 and 24 and adapted to be held in fixed relation thereto by removable studs 174 engaging the upper ends of upright arms 176 on said carrier. The carrier comprises side arms connected by an end piece 178 and a web 180 and each of the rolls 170 is journaled in a box slidable vertically in the side arms of the carrier and spring-pressed to hold said rolls in engagement with the outer surface of the belt 12. The two right-hand rolls, as shown in Fig. 1, cooperate with backing rolls 182 supported in brackets 184 attached to the cross strip 26, while the left-hand roll 170 presses against the belt at a point where it is supported by the roll 16.

To take care of wear of the brush bristles and to insure such an angular relation between the belt 12 and the brushes that there will be ample room for an exit of the pieces of work without disturbance by the brushes, the bracket arms 22 and 24 with all the parts carried thereby may be moved up and down by means of a screw connection to a sliding stud 190 mounted in an auxiliary casing 192 and pivotally connected at its upper end to said bracket arms 22 and 24. A hand wheel 194 is connected by a Worm to the nut 196 by which the position of the rod 190 is adjusted, thus facilitating an accurate positioning of the belt with respect to the plane of the flat-surfaced brushes.

In the use of the machine, after the various adjustments have been effected to raise or lower the brushes as desired and to vary the inclination of the belt 12, and supposing that coating mate-- rial has been supplied to the receptacle 84, the electric motor may be set in motion and successive soles laid upon the belt 12 at its left-han end as seen in Fig. 1. The soles will be carried along the belt beneath the roll 130 and the brushes 32 and 34 and the roll 132, which rolls prevent lateral displacement of the soles as they are coated by the brushes and insure continual progress of the soles with the belt. The soles will be removed from the belt by the work stripper 150 and in accordance with the usual factory practice, will be transferred to a drying conveyor.
